Not “9.5h worked each day.” It’s hours of pay needed in a month for a single renter to cover a bare-bones basket.
Quick anchor with public data: Tel Aviv non-rent essentials ≈ ₪4,470 + studio/1-bed rent ≈ ₪5,000–6,300 ⇒ ≈ ₪9,500–10,700/month. If take-home pay is ~₪45–55/hour, that’s ~175–235 hours of pay. Many Israelis don’t live alone in TA (roommates/partner/subsidies/outside TA), so their effective hours are lower. The chart standardizes a tough single-renter scenario to compare places; it’s not saying people literally work 9.5h/day.
